The Air travel mattress is easy to transport thanks to its lightness and thinness, and features a soft foam core with vertical air channels in the heart of the mattress for comfortable, dry nights. The air channels in the heart of the mattress trap excess CO2 exhaled by the body, preventing the build-up of harmful heat. Optimum air circulation allows the baby to breathe freely and sweat less. 3D air cushions provide optimum ventilation.
